Interesting idea over all...

"for lights ive got these little battery powered led lights"

The weak link...?
ZZTops Reviewed by ZZTops on . ??? Okays this may sound abit insane, but im intrested to see if it works. i came up with this idea, which involveds growing a plant underground. ive buried a reasonable sized bin in the ground, covered the insides in tin foil, cba with paint. and i put a whole roll of clingfilm around the outside, been underground with no plant for a week, no water leaks and is warmer than the ground. for lights ive got these little battery powered led lights, have to change the batteries every 4 days.
